Description Peter Miller 2010-09-29 17:40:14 UTC

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.10) Gecko/20100914 SUSE/3.6.10-0.3.1 Firefox/3.6.10

After upgrading from kernel 2.6.34-12.3 (that comes on the installation disk) to a newer kernel (2.6.34.7-0.3.1) via online update I only get a blank screen after booting (system boots "normally" though). Only when using nomodeset as kernel parameter screen is working properly. Went back and forth between kernels and result is reproducable each time.
Harware is DELL E6510 with Intel Ironlake graphics adapter.

Reproducible: Always

Steps to Reproduce:
1.Upgrade to new kernel via online update
2. reboot -> blank display
3. Use nomodeset as kernel parameter -> display comes back

This is related to Bug #608300. eDP support has been fixed in the kernel updates 2.6.34.4/2.6.34.7 - at least for other laptops like 

- HP Elitebook 2540p (Swatch)
- HP Elitebook <something> (Omega)

I found a related upstream bug:

I have the same problem in openSUSE 11.4 Milestone 5 with Dell Optiplex 980 with two dual head graphic cards.

Symptoms: Grub appears, then initial kernel splash, then screen goes to sleep. Finally X screen appears after several seconds. Ctrl+Alt+F1 causes screen freeze (X display is still visible, but does not react), pressing Ctrl+Alt+F7 returns back.

Summary: Console does not work. Grub, initial kernel splash and X works.

I can provide hwinfo.

Hello,

The same problem for:

eMachines e525.

On splashscreen everything seems to load OK, but screen is very dark and I cannot see anything - but system is loaded OK. When I clcik "CTRL+ALT+DEL" i see windows with menu to Shutdown/Reboot - but it's very dark, almost invisible. After 30 seconds system shutdown perfectly. With nomodeset everything seems to be OK, but with KWIN 3D efects KDE hangs randomly. I can provide lspci, hwinfo etc. 

Greetings

Sorry I forgot to write that for me problem exists after kernel update on 11.3 and even on Live CD in 11.4 and 11.2 Mileston 5. 

I don't know if this issue is relative, or I should create a new one.

greetings

With the coming release of openSUSE 12.2, openSUSE kernel developers are focusing their efforts there. Reports against openSUSE 11.4 and prior will not get the attention needed to resolve them before openSUSE 12.2 is release and openSUSE 11.4 becomes unmaintained.

Please re-test with openSUSE 12.1 or openSUSE RC2+ and re-open with an updated Product if you still encounter your issue.

We apologize for this issue not getting the attention it deserves but we are focusing our resources in the area where they will have the most impact for our users.  We're working hard to make openSUSE 12.2 the best openSUSE release yet!
